The walls still stand to two metres in places, built in roughly coursed drystone rubble limestone, and a limestone slab that once served to block the entrance still leans against the outside of the wall as though someone set it down a moment ago and never returned. But this was a penitential station, a type of site associated with patterns of ritual prayer and physical penance, typically circuits of prayer performed barefoot around a series of sacred points in a landscape. The station sits only 1.6 metres from a feature recorded as St Elba's Grave, and roughly ten metres east of a holy well known as Toberelba. The clustering of these three elements, well, grave, and station house, is characteristic of Irish penitential landscapes, where a spring, a burial, and a place of shelter or focus were drawn together into a loose sacred geography.

The structure itself is small, its interior measuring just under three metres by two, with an entrance just a metre wide set into the north-east wall. The south-west wall is noticeably heavier than the others, at 1.3 metres thick compared to 0.5 metres for the rest, and it projects beyond the corners of the building at both ends. A bulge along its midpoint suggests the wall partially collapsed at some point and was rebuilt, which in itself speaks to a community that returned to maintain the place across time. Whoever patched that wall and leaned the door-slab back against the entrance was investing in a site that still mattered to them. The dedication to St Elba is obscure, the saint not widely recorded elsewhere, which makes this corner of Sligo bog a rare survival of a local cult that might otherwise have left no trace at all.
